As stated, the embodiment of the invention illustrated is especiallydesigned for making the binding tape, the subject matter of the Wall andReinhard Patent 2,570,615. The machine is in some respects an embodimentof and ain improvement on the structure of the patent to Boersma andRobinson No. 2,560,923, issued July 17, 1951.

The binding tape which is designated generally by the numeral I in Fig.4 comprises a metal ribbon or strand element 2, a padding element 3, anda padding backing strip i of paper interposed between the metal strandand the padding. The backing strip 4 is of a width substantiallyexceeding the width of the metal strand and is adhered to the inner sideof the metal strand. The padding, which is desirably formed of multiplytissue folded upon itself, is adhered to the inner side of thesupporting strip 4.

The machine of this application is designed to form the padding element3 (see Fig. 8) from multiply strips of tissue 'I (see Fig. 7) and toapply the supporting strip or element i to the conformed padding stripto produce the composite strip designated generally by the numeral 8 inFig. 9. The composite strip 8 is first formed as a continuous strip andis then cut into sections and adhesively secured to the metal ribbon orstrand element 2 with the adjacent ends of the sections in spacedrelation to each other and spaced relative to the scores 5 in the metalelement indicated in Fig. 4 by dotted lines. These scores facilitate thebreaking or severing of the continuous strip into tie length and providetie sections 6 at each end of the padding. One use of this material isillustrated in the Wall and Reinhard Patent 2,57 0,614.

For convenience and economy in manufacture the operative parts aresupported on frames designated generally by the numerals l0, II, I2, I3and I4, these being arranged in alignment. The frame I0 is designed tosupport a plurality of reels or spools I5 for strips of padding material'I and a spool or reel I6 for the strip of padding backing material 4.As illustrated, two strips of the padding material are employed informing the padding element.

The strips l are guided by the guide rollers Il, conventionally shown inFig. 1, to the forming member I8 which is provided with converging edgefolders I9 which'fold the edges of the padding material upwardly andinwardly into edge the chain 33 and suitable sprockets.

`abutting relation as shown at Eil in Fig. 8. The

padding supporting strip 4 is guided by the roller 2l to the guidethroat 22 disposed in advance of the glue or adhesive applying roller24, this roller dipping into the adhesive receptacle 25. From the glueroller the strip 4 is guided by the guide throat into superimposedrelation to the padding strip and its Vadhesive surface is superimposedupon the inturned edges of the padding strip as is shown in Fig. 9.

The padding material and the backing niaterial therefor is drawn fromthe spools or reels and through the forming dies and across the adhesiveapplying roller by means of the coacting pressure and feed beltsdesignated generally by the numerals 1 and 28, these being supported sothat their opposed reaches travel rearwardly and apply driving andsealing pressure to the composite strip. The belts are trained over therollers 29 and 29 which are gea-red to each other and driven by thechain 34 from the transmission assembly designated generally by thenumeral 3|. This transmission assembly is driven from a motor 32 throughAs the details of this mechanism are not part of this invention they arenot illustrated herein. This first pair of feed and driving belts arethe same in structure as the second pair of feed and driving belts whichare illustrated in more detail v in Fig. 3 and will be described later.

VThe rst pair of feed and pressure belts are of such length as to allowthe adhesive toset before the composite strip is discharged from thebelts. As it is discharged from these belts it is formed into a take-uploop 34 and the loop is given a half twist, as indicated at 35, so thatas discharged over the guide roller 95 the padding supporting element 4is on the under side of the composite strip as shown in Fig. l0, itbeing shown in Fig. 9 in the position in which it is discharged from thefirst pair of feed and pressure belts. The speed of the machine iscontrolled by the hand wheel 31, the sprocket chain 31 and suitablesprockets to the driven shaft of the variable speed transmissionassembly (see Fig. l) The loop is formed by the difference in speed ofthe pad forming machine, and the metallic strip applying machine.

From the roller 36 the composite strip is passed through the guide 38 tothe feed rollers 39 and 49, the feed roller '39 being a driven rollerand the feed roller 4t a pressure roller. At the rear of the feedrollers is a cutter comprising a cutter bar 4| and the reciprocatingcuti ter blade or knife 42. At the rear of the knife is a guide 43having an opening 44 in its under wall through which the glue oradhesive applying roller 45 projects to coact with the paddingV backingstrip 4 of the composite strip 8 which is then in position with itspadding supporting strip 4 downward or on thev under side. The guide 43directs the composite strip with the adhesive thereon to the second pairof the feed and pressure belts 45, the adjacent cooperating reachesthereof traveling rearwardly. A series of belt supporting rollers 41 areprovided for the opposed reaches of the belts so that the belts arefirmly pressed against the work passing therebetween. The ribbon steelelement 2 is` `directedby Vthe guide 48 against the lower belt as itpasses around the front pulley 49, as shown in Fig. 3, so that the metalstrand is directed upon and pressed against Vthe adhesive bearingsurface of the strip 4. The rear ends of the belts 46 are supported anddriven by the pulleys 50 which are geared together, the gears not beingshown.

The lower pulley 58 is driven by the sprocket chain 5i coacting with asuitable sprocket on the jacksha'ft 52.' The metal element or strand 2is drawn from a spool or reel 2 on the frame or pedestal I3. The upperfeed belts of both units are adjustably supported by means of the screws53 for regulating the pressure thereof and adjusting thesame to thethickness of the material used.

The scores, indicated at 5 in Fig. 4, are formed by means of theserrated or toothed scoring blade 54 mounted on the roller 55 in opposedrelation to the supporting roller 56. The roller 55 is provided with abearing member 51 adjustably supported in the frame 58 by means of thescrews 59, only one of which is illustrated. The roller or scoring blade54 is driven in timed relation to the lintermittent feed roller 39 sothat the composite strip sections delivered from the intermittent feedroller and the cutter to the feed and pressure belts are delivered withtheir ends in spaced relation to the scores of the metal strand elementproviding the tie sections ll.

To drive these several parts in timed relation the jackshaft 52 isdriven from the driven shaft of the variable speed transmission by thedriving chaink 59 on the sprocket 6| on the jackshaft. The drivingroller 39 and the glue roller 45 are driven from the jackshaft throughthe chain 92 and a sprocket indicated at 63 on the jackshaft. The shaft64 of the feed roller 39 is intermittently driven'through the clutchdesignated generally by the numeral 65. The details of this clutch arenot illustrated'but it is actuated through the rockshaft 66 having anarm 51 coacting with the clutch actuating member 68. The rockshaft isprovided with an arm 59 with which the cam 10 on the shaft 1| coacts.The shaft 1| is driven through the clutch 'i2 and the sprocket chain 13to the jackshafts 52. 'Ihe clutch actuating arm 14 is actuated throughthe tappet arm 15 which is positioned to be engaged by tappets 16 on thesprocket chain 1l. rIhis sprocket chain is ydesigned to be lengthenedand shortened by taking out one or more links, it being adjustablysupported by the adjustable sprockets 18 (see Fig. 1). The arm 14 isconnected by the link 19 to the clutch actuating arm 8U for the scoringcutter 55. The details of these clutches are not illustrated as theyform no part of the present invention.

The shaft 1l is provided with a cam 8i which coacts with the roller 82on. the lower end of the connecting rod 83 which is supported by the Yrocker arm 84 at its lower end and is connected to the cutter actuatinglever 85 pivoted at 83 and pivotally connected at 81 to the cutter blade42. A spring 88 is provided for retracting the cutter blade.

The feed roller 39 is provided with an overrunning clutch, designatedgenerally by the numeral 89, and with a brake 90. The brake iscontrolled by the arm 9| which is actuated by the link 92 carried by thelever 85. A spring 93 is interposed between the thrust member 94 on thelink and the arm 9i.

To prevent overrunning of the shaft 1i it is provided with a frictiondrag designated generally by the numeral 95. The metal strip element 2is passed over the support 96 with which the microswitches 91are'associated so that in the event of the breaking or runningout ofthestrand 2, the switches are actuated to stop the 'through the cableindicated at |0| (see Fig. 2).

The complete binding tape is passed through the winding guide |02 to thereel |03 which is driven through the chain |04 and suitable sprockets.The Winding guide |02 is carried by an arm |06 which is pivoted at |01and operavtively associated with a cam |08 which is connected by thesprocket chain |09 and suitable gears to the winding reel shaft ||0.
